3 INTRODUCTION US Geo-Explorer is a web-based spatial data service that allows easy access to a rich collection of comprehensive information from US population censuses, US establishment data, and other data sources in a spatially integrated system with many powerful functions for exploratory spatial data analysis. Unlike many other GIS systems and mapping tools, US Geo-Explorer is compatible with most web browsers and does not require advanced GIS skills to learn and operate. With this spatial intelligence, users can generate maps, charts, tables and reports using demographic data from the US for regional planning, business investment, population, housing, environmental assessment, public health and many other spatial studies. Data sources in this database include demographic information for all geographies in the US, including states, counties, metropolitans, CCDs, Places, tracts, blocks, or user self-defined areas. The features of this service include: Efficient data integration for spatial, non-spatial, and text data Quick and accurate location analysis and spatial assessment Identification of spatial patterns and trends Creation of time-saving, easy-to-use, and customized reports Dynamic charts, tables and maps Multiple options for data export to HTM, PDF, Excel, Word, or GIS Shape files The primary data sources for this service include: US 1970 Population Census Data with GIS Maps US 1980 Population Census Data with GIS Maps US 1990 Population Census Data with GIS Maps US 2000 Population Census Data with GIS Maps US 2010 Population Census Data with GIS Maps 3

4 US Business Patterns Data with GIS Maps ( ) US Business Report ( ) US Establishment Data (> 13 Million business records) The basic GIS maps include: US State Boundary Maps US County Boundary GIS Maps US Metropolitan Boundary GIS Maps US CCD Boundary GIS Maps US Place Boundary GIS Maps US Census Tract Boundary GIS Maps US Census Block Boundary GIS Maps 4

5 1. SYSTEM INTERFACE The interface of US Geo-Explorer (UGE) is primarily composed of two frames: Menu bar on the left side and Map bar on the right side (see Figure 1). Figure 1. The Main Interface on US Geo-Explorer. The right side is a map window (Part A), which shows the selected areas of the current map layer. Use the navigation and sliders in Part A to pan, zoom in or zoom out on the map. The top toolbar (Part B) provides several options for map display and spatial data selection. The left side is a menu window. The top toolbar (Part D) allows users to switch the interface language between Chinese and English. The Menu bar (Part C) offers various functions for data selection, report selection, and data export. In Part B, the Map Operation provides a toolbar with several buttons: 5

6 From left to right, the function of each icon shows below: Hide/Open the Menu bar Clear Query Shapes. Identify Pan Zoom In Zoom Out Query by Point Query by Circle Query by Rectangle Query by Polygon The left Menu bar (Part C) provides several options for data selection and map display, which include Administrative Unit, X&Y Location, Chart, Time Series, Establishment, Theme Map, and GIS Map Export. 6

7 2. ADMINISTRATIVE UNIT In the Administrative Unit menu, users can generate a variety of reports based on the selection of administrative units. 2.1 REGION SELECTION ADMINISTRATIVE UNIT SELECTION BY TOOLBAR The first step is to set the regional level by selecting from the pull-down list in Part A (Figure 2). UGE provides seven classes of administrative level: State, County, Tract, Block, Metropolitan, CCD and Place. After setting the region level, the selection can be made by using any query buttons in the toolbar (Part B). As shown in Figure 2, using the Circle Query button in Part B to draw a circle in the map layer causes the selected regions to turn pink and the name of the regions to show in the Selection frame in the Menu window (Figure 3). Figure 2. Administrative Unit Selection Using the Circle Tool. 7

8 Figure 3. The Result of Selection Using the Circle by Query Tool. An individual administrative unit also can be selected and de-selected with a single click using the Query by Point tool ADMINISTRATIVE UNIT SELECTION BY MENU BAR Users also can select the administrative unit using the Menu bar. The Menu bar can be divided into four parts as follows (Figure 4): 8

9 Part A is Selection Mode, which Figure 4. The Menu bar in Administrative Unit. includes Single group mode (default) and Multi-groups mode. Part B is the Regional Level where users can select any level from seven classes. Part C lists all the units corresponding to the regional level specified in Part B. Each selection can be made by either double-clicking the name in the list or by single-clicking the name and then clicking the Add button. Users also can select more Figure 4. The Menu bar in Administrative Unit. than one geographical unit by pressing Shift or Ctrl when selecting. Click the Add All button to select all of the items in Part C. The selections will be displayed in the Selection Frame (Part D). Single-click an item on the list, and the corresponding location will be highlightedon the map. Items in Part D can be removed by clicking the Remove button. The list will be cleared by clicking the Clear button. If switched to the Multi-group from Single group, there will be some changes in the Menu bar (Figure 5, Part A). Users could either use the menu or the toolbar to make selections included in the first group. After the first group is set, click the Add group button to add a second group to which more region slections can be added. Groups can be removed by clicking the Group title and clicking the Delete group button. 9

10 Figure 5. Menu Bar in Multi-group Mode under Administrative Unit Selection. The Group By Index button allows users to divide groups by certain indexes. After selecting the regional units and clicking the Group By Index button, a new dialogue box shows on the next page: 10

11 Figure 6. The Group by Index Function Dialogue Box in Multi-group Mode. Part A (Figure 6) shows all the indexes in three categories: Census Data , Economic Census , and Business Data In Part B, the Number of Classification drop-down menu indicates into how many groups the selected area will be divided. Classification Method provides three different methods for division: Equal Interval, Quantile, and Standard Deviation. The Color Ramp control is used to change color of the map results. After selection, all the information will show on Part C. In Part C, the lightest color indicatesthe lowest ranking area. The Classification Value column gives the range of each group based on the selected index. The Districts column shows the name of the individual group members within the range. Checking the Exclude empty groups box in Part D will exclude any group with no value in the designated ranges. After everthing is set, click Confirm in Part E, and the groups are automatically divided based on the specified index. The group setting options are editable using the options in Part B of Figure 5. The current layer map can be exported by using the Map Export button (Figure 5 part C). When the Map Export button is clicked, a new dialogue box will show as below: 11

12 Figure 7. The Map Export Dialogue Box in Administrative Unit. When all boxes are selected, the map will include a compass and legend, as shown in Figure 8. Maps can also be exported in JPG using the Select an Export Type drop-down menu in Figure 7. Figure 8. Map Export in Multi-Groups Selection Mode. 2.2 REPORT GENERATION After selecting the regions, the next steps are selecting the desired variables and generating the reports or the maps. Reports and maps can be exported in many formats. 12

13 2.2.1 STATISTICAL REPORTS The Report tool provides two categories of reports: Standard Report and Customized Reports, which offer users the option to generate reports with designed methodology or with specific indexes. Standard Reports The Standard Report provides three methods to generate the report: Summary Report, Compare Report and Original Report. Figure 9. The Menu Bar for Statistical Reports. As seen in Figure 9, users can select report type and the specific index by clicking the triangle to the left of the folder icons in Part A. By clicking the box in 13

14 Part B, users can choose whether to include the map in the report. Part C shows the details about user s selection. After choosing the indexes, click the PDF button (or Excel or Word button) to generate the report with PDF file. Single group mode Summary Report In single group mode, all the selections made and the gross and subtotals for each range will be summarized into a single group. For example, if Michigan and Ohio states are selected in single group mode, and the Age Detail Summary Report is chosen, the resulting report is shown in Figure 10. Reports can be produced in HTML, PDF, Excel, and Word. Figure 10. The Summary Report in Single Group Selection Mode 14

15 Part A shows the contents of your selections. In Part B, the total population in the two states was calculated and shown with total number of each gender as well. In Part C, age was divided into groups with range=4, and the subtotal of two state populations in each age group is shown in the list. Compare Report In Compare Report, instead of adding the data in all selections, the report will compare the data between all the selections. Still using the Michigan and Ohio States as the example, Figure 11 shows an Age Comparison Report in compare report mode. Part A shows the basic content of the report. However, in Part B, instead of giving the summary data in two states, this report provides the counts and the percentage of each age group separately, which is convenient in order to compare each age group between the two states. Figure 11. The Comparison Report from Single Group Selection Mode. 15

16 Original Report The basic function of an Original Report is to provide the original data statistics in each selection region and display them ranked in descending order. Continuing to use Michigan and Ohio states, Figure 12 shows an Age Group Report in Original Report mode. In Figure 12, the raw data are listed in each age group and the states are ranked by total population. Figure 12. The Original Report from Single Group Selection Mode. Multi-groups Mode: In Multi-groups Mode, the available reports are All-groups Report and Subgroup Report, each of which can generate a Summary Report, Comparison Report and Original Report. To illustrate these functions, we use two groups, with New York and Maryland states in Group 1 and Michigan and Ohio states in Group 2. All-groups Reports A Summary Report generated in All-groups mode will be identical to a Summary Report generated in Single-Group mode, because both will add up the counts regardless of the groups. By contrast, a Comparison Report will compare the total counts of more than one group. In our example, Figure 13 shows an Age Detail Comparison report in All-groups mode. 16

17 As the table shows, the comparison is processed between the two groups, which each group containing two states. Figure 13. An Age Comparison Report in All group and Multi-group Modes. When Original Report is selected in the same example, the resulting report, shown in Figure 14, will sum the totals for each group. The total value of the group is used as the unit for ranking them in descending order. 17

18 Figure 14. A Rank Report of All Groups in Multi-group Mode. Sub-group Report Sub-group Reports show various relationships within each group. The same selections in regional level and report type are employed here as the example. When the Age Detail Summary Report in Summary Report mode is selected, clicking on the Sub-group button will allow users to download a Zip file (compressed file) containing reports of two individual sub-groups (the format of the report must be selected before the Zip file is produced). Two reports are contained in the Zip file. The Sub-group 1 report is shown in Figure 15. In the Summary Report, the total value of each group will be separately summed up and reported in distinct pages. Here, the red circle in figure shows the difference from the All-groups Report. It also shows the members in the group contained in this Summary Report. The Sub-group 2 Summary Report will be the other file contained in the Zip file. 18

19 Figure 15. Summary Report from Sub-group Report in Multi-group Mode. In a Comparison Sub-group Report, the comparison will be made among the members within each group, and different groups Comparison Reports will be separately shown on different pages. When the Age Detail Comparison Report is selected, clicking the Sub-group button will produce a Zip file containing two reports, as shown below: 19

20 Figure 16. A Comparison Report from a Sub-group Report in Multi-group Mode. The table in Figure 16 shows the comparison within members of Group 1 (comparison of different age groups between New York and Maryland states). The detail operation is the same as Summary Sub-group Report (see Figure 17). The Original Sub-group Report also ranks the members within each group. Different groups Original Report will show on separate pages. The operation is the same as Summary Sub-group Report. In our example, an Age Report under the Original Sub-group Report for group 1, including New York and Maryland, will appear as follows in Figure 17: 20

21 Figure 17. A Rank Report from a Sub-group Report in Multi-group Mode. Customized Report Reports from more specific indexes can also be generated using the Customized Report. Single Group Mode: After selecting the regional levels in Single-Group mode, click the Customized Report button, the dialog box shown in Figure 18 will appear: Figure 18. The Dialogue to Select Indexes in the Customized Report In Part A, users can select Report type, Summary, Compare and Original, similar to those already described. In Part B, users can select the index of the report by using 21

22 different datasets of the Census. There are hundreds of indexes under each dataset that could be used as variables for each type of report. A maximum of 30 indexes can be included in each report. After all the variables are selected, click the desired type of report in Part C, and a Customized Report will be generated. In our example, instead of showing general information about the population level in each age group in Michigan and Ohio, the more specific indexes can show the population of people for the ages. To create an example of this type of report, start by clicking Summary Report, then select the Population from Age 2010 Population Age 0-4, 10-13, and indexes under Age Composition Information of Population Age in Census 2010 shown in Figure 19: Figure 19. Six Indexes Selected for Generating a Customized Report. 22

23 Select the format of the file that you d like to create report (for example PDF), and the customized report will show as following in Figure 20: Figure 20. A Customized Report from Three Selected Indexes. The report can also be displayed and exported in HTML, CSV, Excel and Word formats. Multi-Group Mode When the selections are divided into multiple groups, Customized Reports can also be generated in All-group and Sub-group modes. In the example, New York and Maryland states are in Group 1 and Michigan and Ohio states are in Group 2 in Figure 21, with the same indexes set as in the single-group Customized Report described above. The dialogue box for variable selection will appear as follows in Figure 22: Figure 21. The Screen to Select Multi-groups in the Customized Report in Multi-Group Mode. 23

24 Figure 22. The Dialogue Box to Select Indexes in the Customized Report in Multi-Group Mode. Use the All-groups Report or Sub-group Report button to select the method to generate the reports. The result will be appear as follows: Figure 23. A Customized Summary Report from All-group Report 24

25 Figure 24. A Customized Summary Report from Sub-group Report 2.3 UPLOAD DATA The Upload Data function can be used to import users data by downloading a Excel template for the selected regions or all regions, then adding corresponding data to index selected by user, and uploading the Excel data file into the system in order to create the report, or GIS map. Figure 25.The Upload Data Button in the Menu bar. Click the Upload Data button (at the top right in Figure 25), and the upload data functions screen will be shown in Figure 26. In Part I, there are the functions the user can use to download the template, and upload their own data. Part II is a sample template for uploaded data. Column A displays the codes and column B displays corresponding region names. Columns C and D are the data that correspond to the indexes selected by the user. 25

26 Figure 26.The Upload Data Functions Screen DOWNLOAD TEMPLATE The user can download a template for all regions or selected regions for reference. Clicking the Download Template button in the top left of Part I (Figure 26) after selecting All Regions (default) or Selected Regions. The code of the region level in the template depends on the Level selected in Figure 25. The template will download an Excel data file, which includes all state codes and names if the State Level is selected and All Regions selected (default). Otherwise, if Selected Regions is clicked, it will download a template only for selected regions UPLOAD SELECTED DATA Using the Select a file and Upload button (in Part I of Figure 26) loads the user s data. Before uploading, enter a name in Table Name, then click Select a file and Upload to select and upload the data file with the format as same as the template. After confirming, the data will be added into the system. The limitation for the uploaded data is 26

27 that up to 30 variables (indexes) and 1000 rows are allowed in a table, and the uploaded data will only be available during the current session. Figure 27.The Menu Screen AfterUploading User s Data. The user s data, after being uploaded successfully, will be shown as in Part A (Figure 27). The user can select Indexes from Your Data to create customized reports and GIS maps, similar to use of the data in Part B. 27

28 3. X&Y LOCATION Region can also be specified using the X&Y Location. In the X&Y Location interface, the region can be selected by inputting the latitude and longitude, selecting from the map or menu, or uploading the file with the scale. 3.1 LOCATION SELECTION LOCATION SELECTION FROM MANU Figure 28. The Menu Bar in X&Y Location Mode Click the X&Y Location button on the top menu bar, and the screen will show the default location (Figure 28, Part E). 28

29 In Part A, the boxes on the left are provided to edit the location by entering its name, latitude, and longitude. After that information is entered, click the Add button in Part B and the location information will be displayed on the right. A location on the list on the right side of Part A can be edited by selecting it and clicking the Edit button in Part B. When the Edit button is clicked, the longitude and latitude values for that location will appear in the boxes on the left side of Part A. The selected locations can be removed from the list by clicking the Delete button. When the Clear button is clicked, all locations will be removed from the list. In Part C, users who do not know the desired longitude and latitude can select the location from the list of administrative unit provided. The layers include State, County, Tract, Metropolitan, CCD and Place point. When the State point layer is selected, the search box beside the layer selection slide provides a keyword search function in Part C. After double clicking or using the Add button, the location will be selected and will appear in the box on the right side of Part A with corresponding attributes. On the other hand, when the layer is selected in Part C, the current layer map will automatically show on the right side, with each point standing for each unit. By clicking the point on the map, the location will be added and shown in the list (Part A). Location also can be selected by uploading location files. By clicking the Upload button (Part B), users can upload local files in.txt format. Each line in the text file must contain a name, latitude, and longitude. For example: coordinate1, , coordinate2, , coordinate3, , After selecting the points, the Spatial Range box in Part D allows the user to set the geographic parameters for the information to be analyzed. The Units option in Part D has two choices: Miles and Kilometer. The Range can be set manually, and its default values are 1, 3, and 5, miles. Data will be summarized within concentric 29

30 circles of the specified sizes. When all the options are set, the map with all selected points and their surrounding circles will appear as below: Figure 29. Three Concentric Circles for Each Selection Point LOCATION SELECTION BY TOOLBAR The location can also be selected via Toolbar. The Query by Point icon is activated in X&Y Location interface. After clicking on the desired location, the corresponding name, longitude and latitude will automatically show on the box at the right side of Part A in the Menu bar (Figure30) : Figure 30. Region Selection by Toolbar. 30

31 All the information of the selected point on the map will be automatically shown in Part A, and the radius of three concentric circles can be edited in Spatial Range. 3.2 REPORTS AND GIS MAPS A user s preferred type of report is set using the Customized Report and Standard Report button. There are three kind of report types Summary, Compare and Original. The methods of report generation are consistent with the description in Section 2.2. However, there are some changes that should be noticed: In a Summary Report, all the data, including the counts within the three concentric circles around each selection, will also be included in the sum total. In a Standard Comparison Report, new default variables called 10 mile, 30 mile, and 50 mile, which are the data for the three concentric circles, will be included in the report (see Figure 31): Figure 31. A Comparison Report Generated in X&Y Location Mode. 31

32 Figure 32. Screen Shot for A Comparison Report Generated in X&Y Location Mode. In an Original Report, the ranks are given to all the regions, including the three circles around each selection. Figure 33. A Rank Report Generated in X&Y Location Mode. 32

33 4. CHART Chart mode provides a variety of charts mainly focused on development trends over a defined time period in a certain industry. When accessing the Chart page, in the Part A (Figure 34a or Figure 34b) users can choose Data Theme at the dropdown menu. Population Census is the default theme, and Economic Census and Business Data can also be selected to create charts. Then charts are generated by the regional database for State, Metropolitan, County, CCD, Place, Track, or Block. Figure 34a. The Data Theme Menu in the Charts Function. Figure 34b. The Data Theme Menu in the Charts Function. 33

34 When a regional level is selected, the regional selection is restricted to the corresponding level of administrative unit. Taking the statistics of Population of Different Races in State Census as an example, the interface will appear as shown in Figure 35. In Part A, specific indexes within each category can be selected by checking the box next to the index. In Part B, users can select the desired region in the Region list. The region can also be selected via Query by Point icon on the Map layer. When a geographical unit is selected, statistical charts will be generated and the geographic information will display on the map at the same time. To re-create a new chart, the Reset button in the Part C can be used to restart selecting new indexes. 34

35 Figure 35. The Index Selection in Menu bar of Charts. 35

36 The result appears in Figure 36. Figure 36. The Chart Generated from Selected Indexes. Figure 37 shows the chart generated by using Population of Different Races as the index in Michigan State. In Part A, users can specify the time range by selecting Start date and End date for the chart created, and using the Export button users can export the current chart to a new HTML page. Part B shows the chart created, and Part C indicates the average population of the different races for the selected indexes. Figure 37. The Chart of Population of Different Races in Michigan State from 1970 to

37 5. TIME SERIES Time Series mode provides a variety of reports mainly focused on development trends over a defined time period in a certain industry, the same as Chart mode. UGE can generate reports with time series data. When accessing the Time Series page, the interface is shown (Figure 38). In Part A users choose Data Theme from the drop-down menu. Population Census is the default theme, and Economic Census and Business Data can also be selected to create a report. For Region selection in Part B, the selection method is similar to that described in Section 2.2. First select region level, then select region and all the selections will be shown in the Selection frame in Part C. For spatial lagged variables in Part D, the default value is 1,000 miles. This means that summary data within the circle with radius equal to 1,000 miles will be included as a new variable with the name X_W in the report table. Figure 38. The Menu bar in Report Function of Time Series. 37

38 The next step is index selection as shown in Figue 39. After switching to the Customized Report tab, users can select the variables index on the list in Part A by using Add botton or double click the desired indes. All the selected variables will appear in the box in Part B. The selected variables can be deleted using the Remove button. The entire list can be deleted with the Clear button. Figure 39. Indexes Selection in Time Series Report Function. The third step is to select a desired time period. In the Year tab as showed in Figure 40, users can select the year by double clicking on the year or by using the Add button in Part A, then all the selected years will appear in the box in Part B. Figure 40. Years Selection in Time Series Report Function. 38

39 In the same way, the Remove button will remove unwanted selections and the Clear button will clear the whole list. After setting the region, indexes, and years, click the format of the report file needed from the options HTML, PDF, CSV, Excel and Word (for example, PDF), and the resulting report will be created as shown below in Figure 41. Figure 41. The Report Generated in Time Series. 39

40 6. ESTABLISHMENTS The Establishments menu allows users to find firm level information with more 13 million business records by industries and by region. It can generate charts with either the counts of new establishments for a given year or the cumulative counts for a period. It can also create report for the certain ZIP codes selected. 6.1 ESTABLISHMENT SELECTION BY MENU In the Establishment interface, there are Selection and Report options at the top of the menu. Choosing the Selection option will result in two choices for selection: Simple Search and Advanced Search (default) as showed in Figure 42. For users with ZIP code information, Simple Search is a convenient method. If not, by using the Advanced Search, users can access broader information that can be narrowed down. Figure 42. Search Screen in Establishment Mode. 40

41 6.1.1 SIMPLE SEARCH Selecting the Simple Search option, users can type in the ZIP code in the search box and click search button (see Figure 43). Subsequently, the search results are shown in Figure 44. Figure 43. Simple Search Figure 44. The Establishment Simple Search results for ZIP code

42 In Part A, users can use the pull-down list to limit the industries displayed, and the number of establishments will automatically adjust to the total counts in the selected industries located in the ZIP code. Users can return to the search menu by clicking the Back to Search button. In Part B, all the names of establishments in the selected industries are listed. Further information about each enterprise can be acquired by clicking its name. After selecting the desired industries, users can use the Plot from Starting Year button in Part E to obtain the time series chart. The ZIP code entered will show in Part D. The list can also be exported in an Excel format by clicking the button in Part C. When the name of an establishment is clicked, a new dialogue box will be shown in the right of Figure 45 as an example when clicking Ann Arbor District Library on the left of Figure 45. Figure 45. The Dialogue Box with Detailed Information of Establishment. At the right in Figure 45 is detailed information about the establishment. Users can click Go to Location Selection at the bottom, bottom find X&Y location, and also can use two search engines (Google, and Bing) located at the bottom of the dialog box for a more detailed search. 42

43 When the Plot of Starting Year button in Part E (Figure 44) is clicked, a new dialog box will appear: Figure 46. Plot of Number of Establishment within Selected Region. When the Cumulative establishment button is selected in Part A of Figure 46, the display will switch from the counts of the establishments in each year to a cumulative count of establishments. In Part B, users can select Start year and End year to restrict the range of the plot. The PDF or EXCEL button can be used to export the chart ADVANCED SEARCH In Advanced Search, the location can be selected by providing more general information (see Figure 42). From State on the top to CCD at the bottom, all the rows provide pull-down lists from which to select. To avoid a range that is too large, at least the information above the CCD should be provided. Users can also directly input the ZIP code or the name of establishment into the boxes. After making selections and clicking Search, the whole list of establishments will appear in the Menu bar. As an example, the list in Figure 47 was generated by choosing Michigan in State, Washtenaw in County, and Ann Arbor in CCD in the Advanced Search page. 43

44 Figure 47. The Establishment Search Result within Michigan State, Washtenaw County and Ann Arbor city. 6.2 LOCATION SELECTION BY TOOLBAR Selection from the map is also available using the toolbar. By single-clicking some points or drawing a shape on the map using the location selections in Part A (Figure 48), the establishments in the selected area will automatically show in the list on the Menu bar. No more than 20 ZIP code points should be selected at once. After selection, the list of establishment is the same as the menu selection in Figure

45 Figure 48. The Location Selection in Establishment via Query by Point Icon in Toolbar on Map. 6.3 REPORT A report can be generated by selecting Report tab. Users can select one or more ZIP codes using the ZIP button, and select one or more indexes using the Index button (Figure 49 and Figure 50). Then, select Report Type from Summary, Compare and Original, and export the report by clicking any Output option from HTML, PDF, CSV, Excel and Word format. Figure 49. Select ZIP Codes for Generating Report in Establishment Function. 45

47 7. THEME MAPS UGE can generate spatial distribution maps based on certain indexes. In the Theme Map, a thematic layer map can be generated to represent distinctive classifications corresponding to a selected index. The Menu bar and the map on the Theme Map page is shown in Figure 51. In Part A, the pull-down list is provided to select the regional level as the unit for classification. Users can choose the index from all the census lists in the lower box in Part A. Part B provides the options to modify the Theme Map with the user s desired method of classification. After selecting an index in the list in Part A, the Theme map title in Part B will automatically be filled. Part D allows you to switch the map extent between all regions and selected regions. When clicking the selected regions, only regions selected will be shown on the theme map on the right side in Figure 51. Figure 51. The Menu Bar and the Map in the Theme Map. However, users can edit the title by re-typing it in Part B. Users can also change the number of classes from the pull down list in Number of Classification. Classification Method provides three methods used to calculate the range of each 47

48 class: Equal interval, Quantile, and Standard Deviation. Color Ramp provides colors for the Theme map layers. The Transparency indicator can be used to adjust the transparency. When all the indexes and methods are fixed, the bottom table in Part C will give detailed information about the range of each class, as shown in Figure 52. Figure 52. The Detailed Information of Each Class with the Index State_2010 Population. Single-clicking each color icon in the color column can change the color from the default. The map on the right side is continuously updated as parameters are changed. The rectangle on the right side of Figure 53 shows the options for the layers on the map. By un-clicking the box under Theme Layer List, the map will return to the original one with no layer created based on the chosen indexes. By de-selecting the Open Street Map under Basic Layer List, the bottom street map will be hidden. When items in the Reference Layer List are deselected, the corresponding layers in the map will be concealed. 48

49 Figure 53. The Theme Map Generated by Selected Index. After all the indexes and methods are set, click Map Export button in Part D (Figure 50) and the Theme Map will be exported into a new PDF or JPG file. The Reset button can be used to re-start generating a new theme map. Users can also import their own data set to generate a theme map by using Upload Data button. The Theme Map can be used as a basic layer for further operation. For example, if a user creates a Theme Map and then switches to the Administrative Unit page to select locations or generate reports, the Theme Map will be saved as the current map, while all other selection methods are still available. 49

50 8. GIS MAP EXPORT The GIS Map Export function generates files in formats including files.shp,.xls,.shx, projection files, and metadata table for variable list necessary to create base maps in ArcGIS software for further analysis. Click the GIS Map Export menu at the top menu bar, first select a geographical area and data sources, such as Administrative units, X&Y locations, or Time series for Population Census, Economic Census and Business Data. Then click the GIS Map Export button in the left window (Figure 54). Figure 54.The GIS Map Export Button in the Menu bar. 50

51 A new dialogue box for index selection will be shown as follows: Figure 55. The Dialogue Box in GIS Map Index Selection.
